The leachate produced flows in different layers of waste and carries toxic and polluted substances to surface or groundwater. Kacha River, which carries the contamination load from Saravan landfill, flows into Siahrud River; Siahroud passes through this lands on its way, flows to the north and after joining Goharroud, enters the eastern part of Anzali Wetland. In this study, sampling stations were located in Saravan landfill and Kacha River and sampling was done in winter and summer and COD, BOD, TDS, pH, EC, ammonia, phosphate and nitrate parameters were measured. Comparison of the results of leachate analysis of Saravan landfill and Kacha River in summer and winter showed that all parameters, including BOD and COD parameters, which are indicators of contamination load in the Kacha River, increased in the drought season (summer) compared to the wet season (winter) Which indicates the amount of more pollution from Saravan landfill to Kacha River and from there to Gohar River and finally Anzali wetland.
